为解决化学药剂控制水田杂草所带来的环境污染及杂草抗药性增强等危害，设计了一种栅条式水田行间除草装置。同时，对其工作原理进行了阐述，通过运动学分析，推导了栅条的运动轨迹方程，并在试验台上进行试验研究。试验结果表明，该装置可一次性完成对杂草的压、翻、埋等作业，且在栅条个数为10个、栅条宽度为30 mm、除草深度为50 mm时，除草效果最佳，除草率可达81％，满足水田作业除草性能的要求。%To solve the problems of environmental pollution , increasement of weed resistance brought by heavily using herbicide to control weed for paddy field , a grid inter-row weed control device for paddy field was designed and its kine-matics was analyzed ,obtaining the kinematic trajectory equation .Grid, which made weeds pressed , turned and buried in the soil in the process of weeding , is the key part of the device , the results of test in soil bin showed that when the num-ber of grid was 10, the width of grid was 25 mm and weeding depth was 50mm, the effect of weed control was best , and weeding rate could reach 81%.
